Abstract

The invention relates to a vibration mill, in particular to a variable-rigidity double-mass vibration exciter type common vibration mill or super-huge vibration mill, belonging to the technical field of vibration utilization engineering. The vibration mill comprises an upper mass, a lower mass, a motor, a motor base, a coupling, a coupling guard, a master vibration spring, a vibration isolation spring and a base, wherein the upper mass comprises a barrel, a feed port, an end cap, a discharge port, a vibration exciter, a right connecting frame, a milling medium, a left connecting frame and a counterweight body; the upper mass and the lower mass are connected through the master vibration spring, and the inner diameter of the master vibration spring is matched with the outer diameter of a guide pillar of the master vibration spring on the upper mass and the lower mass; and the lower mass is supported on the base through the vibration isolation spring. The barrel can be actively supported on the lower mass through the master vibration spring, and the vibration exciter is rigidly solidified on the right side of the barrel by using a right coupling bracket.

Description

technical field

[0001] The present invention relates to a vibrating mill of variable stiffness two-mass exciter type extra-large vibrating mill, in particular to a general vibrating mill or extra-large vibrating mill with variable stiffness, two-mass body and exciter excitation form, belonging to Vibration utilization engineering technology field. Background technique

[0002] Vibrating mill is a vibrating mechanical equipment that uses the principle of vibration to complete material crushing operations. Ordinary vibrating mills are composed of one or more cylindrical or other shaped containers supported on springs. This container either rotates at the center of gravity or passes through multiple The exciter tuned on the center of gravity performs an unbalanced motion similar to circular vibration, and the grinding medium (the material to be ground and the medium) installed in the mill container collides and rubs, and the crushing is due to the friction between the grinding ...
